SPINNING-MACHINE.

Specification of Letters Patent.

Patented J an. 9, 1912.

Application filed August 3, 1905. Serial No. 272,560.

T all whom it may concern:

Be it known that I, SEBASTIAN ZIANI on FERRANTI, a subject of the King of Great Britain and Ireland, and residing at 31 Lyndhurst road, Hampstead, London, N.W., England, have invented certain new and useful Improvements in and Relating to Spinning-Machines, of which the following is a specification.

The invention relates to spinning, doubling, twisting and like textile processes hereinafter referred to generically as twisting The invention, though not restricted to such an application, 'is specially advantageous when used in connection with the I spinning machine described in my Patent One object of the invention is to'provide a ready means for imparting a right or left hand twist to the material at will.

Another object of the invention is the provision of means for the simultaneous control of a number of turbines each driving its own spindle.

Another object is the provision of simretarding a lagging part; Fig. 6 shows a detail of the means employed for simultaneously varying the operative action of a plurality of sets of feed rolls, one of the friction wheels being removed to show forked lever, while Fig. 7 shows a general view of one form of the entire machine, and Fig. 7 a cross-section on the line A B of Fig. 7 to an enlarged scale showing telescopic drive The drawings are to a-large extent of a diagrammatic nature, while corresponding parts in the different figures are denoted by the same reference symbols.

In carrying the invention into effect according to one form as applied to a twisting machine having leading and lagging parts; the leading part, (see Figs. 1 and 2,) consists of a ring flier, a, having mounted thereon rings, 6 and c, of oppositely disposed turbine blades. Nozzles, d and e, are arranged as shown to cooperate with these sets of blades, one for each direction of rotation. The ring flier runs with air lubrication in an accurately turned sleeve, f, which by way of rubber rings, h, is supported in the housing or casing, 2', of the ring flier, this casing, i, being in turn supported in the rail, j. The exhaust of the turbine serves to take a proportion of the dead underside of its flange, is, past which it finally escapes. In order to slow down or stop the ring flier without removing this air support, baflles, m, arranged on a pivoted arm, n,'may be employed, which by operation of the arm on which they are mounted can be disposed to a greater or less extent between the nozzles and the turbine, thereby to a certain extent cutting off the supply of motive fluid thereto. The arms, 11., may be operated in any convenient manner,'such for example, as by the rod, 0, having a collar, p, which engages with the tailpiece, 7 when moved longitudinally, a spring, 8, serving to replace the batfle.

In order to control a number of turbines fitted one each to their corresponding spindles, I-may divide the main air supply, 2, (see Fig. 3), into two branches, u and o, a three-way valve, to, being placed at the junction point-of the branches. The one branch, u, is provided with a series of nozzles, m, for one direction of rotation, while the other branch, 2:, is provided with a sec- 0nd series of nozzles, z, for the other direc- 7 tion of rotation. By operation of the valve, to, it willbe seen that working fluid may be led simultaneously to all the turbines in either direction of rotation at will. This device involves only one valve for a set of turbines.

A development, however, of such an arrangement is shown in Fig. 4, where the branch pipes, u and o, as before, lead air to the nozzles, w and-z. Each of these nozzles is controlled by a valve, those for one direction of rotation being indicated at 2, and those for l the other direction at 3. The master valve, 'w, asbefore controls all the valves, 2 and 3, all the valves bein linked together as indicated in the figure by rods, 4, and bell cranks, 5, so that by operation of the handle, 6, the one set of valves, 2, can be rendered inoperative and the other set, 3,

' simultaneously rendered operative.

trough-shaped rails, 10, containing gearing,

11, which connects the spindles to the shaft of square cross-section, 12, transmitting motion to the feed rolls, 13. The shaft, 12, carries at its upper end a friction wheel, 14:,

A 30. The effect of moving the magnet up or. down is to vary the reluctance of the mag- 1 it a hand wheel, 36, this shaft carrying the.

. splined thereon, which engages with a friction disk, 15, fixed to the lower roll, 13. Any suitable gear is provided for traversing the friction wheel, 14, across the disk, 15, that indicated by way \of example consisting of a forked lever, 16, carried on the shaft, 17, and operated by a worm quadrant, 18, worm, 19, and hand wheel, 20. Reversal is obtained by moving the friction wheel, 14:, across the surface of the friction disk. As seen in Fig. 6, the shaft, 17 may be common to a number of spinning units, and have mounted thereon a corresponding number of levers,.16, so that reyersal is effected simultaneously in the different units, by operation of the hand wheel, 20. The trough-shaped rails, 10, as described may be conveniently mounted one at the front and the other at the back of the machine, being supported at the end of a see-saw lever, 22, operated by way of the links, 23 and 24, from the heart-shaped cam, 25, and co-acting roller, 26, the cam being driven by any convenient means independent of the. twisting motors.

In order to impose a certain amount of drag on the lagging part, a device, 27, (see Fig. 5,) similar to the squirrel-cage rotor of an induction motor, may be mounted on thelower end of the spindle. This rotor is disposed between the jaws of an electromagnet, 28, provided with energizing coils, 29. A screw, 30, (see also Fig. 7,) having a worm wheel, 31, passing through the bend of the magnet and being operated by the worm, 32; lugs, 33, passing over pins, 34:, may be fitted on the magnet, so as to guide it when moved up and down by the screw,

netic circuit, and thus the drag on the spindle. As will be seen in vFig. 5, a number of such magnets may be operated from a common shaft, 35, having mounted upon worms, 32, which gear with the operating screws of the magnets. As seen in Fig. 5,

the lower member of the telescopic shaft, 12, may conveniently be disposed within the bend of the magnet, 28.

The main air supply, (see Fig. 7,) is shown at 37, branch pipes, 38, controlled by valves, 39, operated for example by the pull rods, 40, distributing the motive fluid to the different turbines.

The parts so described are mounted on any suitable frame, 4%, forming a support for the different twisting units.

The general operation of the complete machine is as follows: The thread from the bobbins, 41, retarded to a proper extent by the box-shaped floats, 42, immersed in water in the troughs, 43, passes by way of the feed rolls, 13, through the anti-ballooner, 8, to the hook, 7, of the ring .flier. The bobbin on which the material is to be wound, mounted on the spindle, 9, is drawn around by the thread and reciprocated by the mechanism shown, its motion bein transmitted by the telescopic shaft and friction gear to the feed rolls. The twisted material is'in this way evenly laid upon the bobbin. Supposing now it is desired to change the direction of twist from right hand to left hand, the right hand set of turbine nozzles will be rendered inoperative and the left hand set rendered operative by meansof any of the controls described. This alteration alone, however, would have the effect of altering the direction of rotation of the feed rolls, and in order to maintain their direction constant the hand wheel, 20, is actuated so as to move the levers 16, and thereby move the friction wheels 14, across the disk 15, from one side of the center tothe other. In this way the directionof twist is altered while the direction of feed is maintained constant.

Although Ihave described the best way known to me of carrying my invention into effect, nevertheless such example is to -be taken as merely illustrative and is not intended to restrict the scope of the invention.

Having now described my invention what I claim as new and desire to secure by Letters Patent is c 1. In a machine for twisting fibrous material, the combination of a rotatable twisting element; 'means'acting to transfer said material in a certain direction; a driving connectionbetween said twisting element and said transferring means; means for driving said twisting element in either direction at will, together with means for maintaining constant said certain direction of transfer.
